中文摘要：

在傅里叶变换轮廓术测量方法中,测量系统从一个角度投影结构光场,系统中的成像装置从另一个角度获取由物体高度调制后的变形光场,并通过傅里叶变换、频域滤波和傅里叶逆变换恢复出物体的高度信息。FTP测量方法中,关于傅里叶变换,相位展开的相关知识,涉及大量复杂的数学运算使其抽象难以理解。针对这一问题,文中设计了基于Matlab的仿真实验。根据相应原理编写了仿真代码,运用Matlab的数学运算和可视化功能,模拟整个测量流程,完成了仿真实验。这有助于学习和理解FTP测量方法原理及相关知识。

英文摘要：

In the method of Fourier transform profilometry （ FTP）, the measurement system obtains the deformation of the object height modulated light field by the imaging device, and restores the height information of the object through the Fourier transform, frequency domain filtering and Fourier inverse transformation. The Fourier transform and phase unwrapping knowledge in the b-TP measurement method involves a large number of complex mathematical calculations, making it abstract and difficult to understand. In view of this situation, we design simulation experiments based on Maflab and prepare the corresponding simulation codes. The entire measurement process is simulated by using Maflab numerical calculation and visualization function, which helps to understand the principles of the FTP measurement.
